With reference to Fig. 3, oil feeding reservoirs 39 is oil supply systems of oily hydrostatic spindle structure.The oil pump 53 of oil supply system is connected with coarse filter 52 and immerses oil sump 51, oil pump 53 is connected with retaining valve 57, surplus valve 54 respectively, retaining valve 57 links to each other with fine filter 56, tensimeter 55, pressure switch 58 respectively through pipeline, enters the throttle orifice of two hydrostatic bearings (referring to Fig. 4) respectively through the pressure oil Ps of fine filter 56.But oil pressure mat surplus valve 54 is adjusted.When operation work, if when causing that because of certain fault charge oil pressure Ps is lower than the pressure of setting, pressure switch 58 can cut off the motor power of drive shaft 37 automatically, and drive shaft 37 is stopped operating.
With reference to Fig. 4, drive shaft 37 places the main shaft housing 59 of body 44.Main shaft 48 front ends have internal taper hole, join with interchangeable axle 47, and hydrostatic bearing 49 is near main shaft 48 left end flanges, and hydrostatic bearing 50 is near thrust circle 60, and thrust circle 60 is compressed by clamp nut 61.Between the side of hydrostatic bearing 49,50 and main shaft 48 flanges, thrust circle 60 certain interval is arranged all, form the axial static pressure of main shaft chamber, respectively there is end cap 62 at main shaft 48 two ends, and are fixed in main shaft housing 59, and only oil seal circle 47 is housed in the end cap 62.
Pressure oil P when oil supply system
1After entering the throttle orifice of hydrostatic bearing 49,50, in hydrostatic bearing 49,50, produce radially static pressure, supporting spindle 48.A continuous forced feed part flows back to oil sump 51 through hydrostatic bearing 49,50 inboard axial seal limits, and the pressure oil that flows to hydrostatic bearing 49,50 outsides forms axial oil static pressure chamber with main shaft 48 flanges and thrust circle 60 sides respectively, and have certain rigidity, can prevent the axial motion of main shaft 48.
With reference to Fig. 5, Fig. 6 and Fig. 7, the effect of rackwork 36 is according to the measuring position needs, and sensor 35 is adjusted on the desired location.Sensor 35 by screw retention on the vertical slipper 65 of rackwork 36.
The horizontal position adjustment of sensor 35 is to rotate handwheel 73(referring to Fig. 7), driven gear 74, gear 74 moves on the tooth bar 75 that is fixed in main shaft housing 59, drives gliding mass 66 horizontal shifts, and the displacement guiding is to be guaranteed by a pair of dovetail guide on gliding mass 66 and the main shaft housing 59.The horizontal location of gliding mass 66 is the handles 69 that are loaded on gliding mass 66 by turn, holds out against wedge bar 76 between dovetail guide through screw, fixes the horizontal level of gliding mass 66.
The upright position adjustment of sensor 35 is to shake handle 72(referring to Fig. 5, Fig. 6), driving bevel- gear sett 71,70 rotates, screw mandrel 67 through being solidified as a whole with bevel gear 70, nut 68 is produced to move up and down, thereby drive the vertical slipper 65 affixed with it and do moving up and down of vertical direction, vertical slipper 65 mobile guides are to be guaranteed by a pair of dovetail guide on vertical slipper 65 and the gliding mass 66.The location of vertical slipper 65 can be by turn handle 64, through bolt the lead-in tension and compression between dovetail guide on dovetail face, fix the upper-lower position of vertical slipper 65.
The vibration measuring operation steps is as follows:
Measured bearing 6 is enclosed within on the interchangeable axle 47: release handle 19 and attachment screw 8, adjust worm drive and pay 21, slide unit 18 is moved in the desired direction, by support 38,17 and the bearing 25 affixed with slide unit 18, drive lever 15, suspension bracket 14 and rotating shaft 26 respectively, and drive bearing holder (housing, cover) 13, rotating shaft 31 and worm drive thus and pay 8,9 and tooth bar 23 same moved further.Adjust to when making the width intermediate point of radial loaded power by measured bearing 6 when slide unit 18 positions, turn handle 19 makes slide unit 18 location, and trip bolt 8 to make framework and worm drive pay nut 9 affixed, then, mobile briquetting 3 makes flexible block 4 contact with measured bearing 6 outer rings, and is again that briquetting 3 is fixing.Adjust rackwork 36 again.Release handle 69 is rotated handwheel 73, makes the measuring head of sensor 35 be positioned at the middle upper part place of measured bearing 6 outer ring width, and set lever 69 again; Release handle 64 is rotated handwheel 72, and sensor 35 is moved down, and the loudspeaker in electronic box 1 is sounded, measuring head contact measured bearing 6 outer rings of expression sensor 35, and then rotate handwheel 72, give the certain volume under pressure of sensor 35 after, set lever 64 again.
Shake the handle on the sector gear 28 downwards, make arc-shaped slot left end on the sector gear 28 register pin 24 that reclines, then sector gear 28 driven gears 30 and bevel- gear sett 32,11 and worm drive pay screw rod 10 rotations, paying nut 9 through transmission drives framework 7 again and vertically moves down, flexible block 4 on the framework 7 compresses the outer ring of measured bearing 6, at this moment sector gear 28 proper and gear 30 drop out of gears.Meanwhile, sector gear 28 promotes tooth bars 23 and moves to right (Fig. 2), makes wedge piece 41 on the tooth bar 23 away from rolling bearing 42, under the effect of weight 43, lever 15 is rotated around the pin joint of support 38.The platform that accounts for of lever 15 is the weight quality with loading force F=L/1 * mg(m) press to the ball point 16 on the suspension bracket 14, apply radial load by the flexible block on the framework 74 to measured bearing 6, and form the stand under load district at measured bearing 6 first halves.
Then, starter motor drives the rotation of measured bearing 6 inner ring constant speed through drive shaft 37, and measured bearing 6 outer rings compress constraint because of being subjected to flexible block 4, are defined motionless.Sensor 35 converts the measured bearing 6 picked up to behind voltage signal input electronic box 1 along the vibration of radial direction, and the electric wiring in electronic box 1 shows vibration measuring value um/s after the computing by oneself.
After recording vibration values, upwards shake the handle on the sector gear 28, make arc-shaped slot right-hand member on the sector gear 28 register pin 24 that reclines, sector gear 28 driven gears 30, bevel gear 32,11 and worm drive pay screw rod 10 backward rotation, make on the framework 7 and move.Simultaneously, sector gear 28 promotes tooth bar 23 and moves to left, and makes the wedge piece 41 on the tooth bar 24 lift weight 43 by rolling bearing 42, makes the lever off-load.At this moment, the flexible block 4 of framework 7 also leaves the outer ring of measured bearing 6, takes off measured bearing 6 then.
